Wednesday 3 September at 11:10 : Nico Rosberg has once again confirmed his intention to stay with the Williams team in 2009, but highlighted his desire for a better car.

"It is quite difficult at the moment, but I will definitely be here also next season," the German is quoted as telling Bild newspaper.

Rosberg, 23, ended his recent points drought with eighth place at Valencia two weeks ago, but before that he was just fourteenth in Hungary.

"I am extremely ambitious. 13th or 15th places do not interest me," he said.

"The team this year has given me a good car only for the three street races. And for one of those I was on the podium," the publication quoted him as saying at the Bad-Nauheim sports fitness clinic in Germany.
